Scum settings - logon data tab.

SCUM SETTINGS - LOGON DATA TAB has the following settings as below:

Global	You can only maintain the data in the central system. The data is then automatically distributed to the child systems. These fields do not accept input in the child systems, but can only be displayed. All other fields that are not set to “global” accept input both in the central and in the child systems and are differentiated only by a different distribution after you have saved.
Proposal	You maintain a default value in the central system that is automatically distributed to the child systems when a user is created. After the distribution, the data is only maintained locally, and is not distributed again, if you change it in the central or child system.
RetVal	You can maintain data both centrally and locally. After every local change to the data, the change is redistributed to the central system and distributed from there to the other child systems.
Local	You can only maintain the data in the child system. Changes are not distributed to other systems.
Everywhere	You can maintain data both centrally and locally. However, only changes made in the central system are distributed to other systems, local changes in the child systems are not distributed.
